Abstract

PROBLEM TO BE SOLVED: To prevent a container from being inflated because of pressure of gas by a method wherein fermentation gas passing through vent holes formed at the central area of a lid that seals up a container is deodorized, and the deodorized fermentation gas is discharged. SOLUTION: A deodorizing means 40 made up by adsorbing a liquid component containing a wool wax acid and a glyceride mixture of a non-side-chain type fatty acid to a porous circular sponge is arranged at the inside of a circular recess 22 at a fluid part for gas. Fermented foods such as Korean pickles in a container 5 autonomously produce gas by fermentation in the process of markatting or distribution. The fermentation gas produces odor while increasing pressure at the inside of the container 5. The produced fermentation gas passes through a number of vent holes 24 formed at the fluid part for gas and goes through the deodorizing means 40. After deodorizing in such processes, the fermentation gas is discharged to the outside of the container through a discharge port 55 of an attachment label 50. Since the pressure at the inside of the container 5 is kept constant because of discharge of the fermentation gas, the packaging container 5 is not inflated.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fermented food packaging container, and more particularly to a fermented food packaging container which is expanded by fermentation during a distribution process by providing a fermentation gas discharging means in a lid for sealing the packaging container. The present invention relates to a fermented food packaging container capable of preventing odor.

[0002]

2. Description of the Related Art Generally, various fermented foods are distributed in the market, and especially, kimchi is mass-produced in factories and sold on the market. Such commercially available kimchi has gained popularity in busy modern homes and has been made available for export overseas.

[0003] Accordingly, various packaging means have been developed to make commercially available kimchi available for distribution for a certain period of time. In consideration of the fermentation characteristics of kimchi, the packaging container of kimchi must have tightness, deodorizing property against fermentation gas, and compatibility with fermentation pressure, and this is a key point in sales.

[0004] As typical examples of conventional kimchi packaging containers for distribution, there have been those that cover a glass bottle and those that use a polyethylene plastic bottle having the same shape as the above-mentioned glass bottle.

[0005] However, the above-mentioned glass bottle is not suitable for distribution because it has a drawback that it is expensive and heavy and easily breaks, and the plastic bottle is also expensive and has poor sealing properties. There was a danger of leaking and causing an unpleasant smell in the sales floor.

FIGS. 1 and 2 show a conventional kimchi packaging container for solving such a problem, that is, a disposable packaging container 100 including a main body 110 of a soft polyethylene resin material and a lid 120 of a film material. , A standing pouch-shaped packaging container 130 is shown.

The packaging container 100 made of the above polyethylene resin material
Is that the main body 110 is lightweight and inexpensive,
0 has the advantage of being excellent in airtightness, but gas is generated by the aging fermentation of kimchi during the distribution process and the container 100
As a result, not only the consumer's desire to purchase is reduced and the merchantability is reduced, but also the container may be ruptured.

Although the standing pouch-shaped packaging container 130 has the advantage of being able to be degassed under reduced pressure and maintaining airtightness, the container expands due to the pressure of fermentation gas generated by ripening, so that it is commercially available. Decreases, and
In use, the posture was unstable due to the height of the packaging container 130, and was still unsuitable as a kimchi packaging container.

[0009]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems.
Airtightness is maintained during the distribution of kimchi, and by deodorizing and discharging the fermentation gas to the outside, the container expands due to the pressure of the gas generated during the fermentation, resulting in a decrease in commerciality. It is to provide a fermented food packaging container which can be prevented.

[0011]

FIG. 3 shows a first embodiment of a fermented food packaging container according to the present invention. The container 5 is formed of a light material plastic, and contains therein fermented foods such as kimchi.

The gas flow section 20 is formed on the lid 10 that seals the container 5 and includes a circular recess 22 and a through hole 24. The circular recess 22 is finely depressed and formed at a central portion of the lid 10 with a certain radius, and a large number of the through holes 24 are formed on the circular recess 22.

The deodorizing means 40 is for removing the odor of the fermentation gas, and is a liquid component containing a glyceride mixture of woolwax acid and non-side chain fatty acid, or a conventional liquid deodorant ( Deodorant) is adsorbed on a porous circular sponge and is provided in the circular recess 22 of the gas flow section 20.

The attached label 50 is attached to the upper surface of the lid 10 and the deodorizing means 40, and the outlet 55 is formed at the center of the attached label 50.

Hereinafter, a method of packaging the fermented food packaging container according to the first embodiment of the present invention will be described.

First, after putting fermented food in the container 5,
As shown in FIG. 4, an adhesive in which a solvent is dissolved, for example, hot melt, is applied to the contact surface of the lid 10.
Then, after the lid 10 is brought into contact with the container 5, if high-frequency welding or pressure welding is performed while applying a constant pressure to the contact portion, the container 5 is air-tightly bonded to the lid 10. This is a method for solving the conventional problem that the kimchi ripening rate is accelerated by the heat of welding and the distribution period is shortened in the case of packaging in which the contact surface is heat-welded. Is exposed to less heat, the distribution period of the food product is extended, and the airtightness is similarly maintained, while the food is more easily opened.

Next, the first embodiment of the present invention will be described with reference to FIG.
The operation and effect of the fermented food packaging container according to the example will be described.

In the process of marketing or distributing the hermetically sealed packaging container containing the fermented food, the fermented food, for example, kimchi, in the container 5 itself produces gas by fermentation. Such fermentation gas generates an odor while increasing the pressure in the container 5. The generated fermentation gas is deodorized in the process of passing through a plurality of through holes 24 formed in the gas flow unit 20 and passing through the deodorizing means 40, and then is discharged from the container 5 through the outlet 55 of the attached label 50. Is discharged. Since the pressure in the container 5 is kept constant by the discharge of the fermentation gas, the packaging container does not expand during the distribution process and does not lower the consumer's purchase desire.

The attached label 50 has an accommodating portion 56 formed to partially protrude upward for accommodating the deodorizing means 40.

Hereinafter, a second embodiment of the present invention will be described with reference to FIG.
The operation and effect of the embodiment will be described.

The fermented gas generated from the fermented food in the container 5 reaches the circular recess 22 through the through hole 24 due to the increase in the internal pressure. The circular recess 22 is used when the packaged container 5 shakes abruptly during the distribution process and the kimchi liquid in the container 5 leaks through the through hole 24.
Prevents contact with 2. That is, the kimchi solution is passed through the through hole 2.
In the case where the kimchi liquid leaks out of the circular concave portion 22, the kimchi liquid flows again into the container 5 through the through-hole 24 by leaving the liquid leaking out of the circular concave portion 22.

The fermentation gas that has reached the circular recess 22 is:
As the internal pressure of the container 5 gradually increases, it passes through the inner diameter of the annular deodorant 42 through the first discharge passage 26 and proceeds to the outer diameter. Here, the fermentation gas flows into the second discharge passage 28 after being deodorized by the annular deodorant 42. Thereafter, the fermentation gas is discharged through the second discharge passage 28 to the outlet 6.
5 is discharged outside.

Hereinafter, a third embodiment in which a sterilizing function is added to the fermented food packaging container according to the present invention will be described with reference to FIG.

In this embodiment, a sterilizing function and an oxygen adsorption and deodorizing function are added between the first discharge passage 36 and the second discharge passage 38. The gas flow part 2 formed on the lid 10
Numeral 0 is composed of a large number of through holes 34 and a rectangular recess 32, and the deodorant bag 44 is accommodated in the rectangular recess 32. The deodorizing bag 44 is filled with solid particles of an activated carbon component to remove the odor of the fermentation gas.

One end of the first discharge passage 36 is connected to the rectangular recess 3.
2 communicates with one side.

One end of the second discharge passage 38 communicates with the other end of the first discharge passage 36, and the other end is branched and formed.

The liquid deodorant 46 adsorbs ferric oxide (Fe ₂ O ₃ ) having an oxygen adsorption function and a deodorant (Deodorant) having an antibacterial and deodorizing function to a sponge built in a tube. The first discharge passage 36 and the second
It is located at a connection site between the discharge passage 38 and the discharge passage 38.

The discharge port 75 is the other end of the second discharge passage 38 and is formed on the periphery of the attached label 50.

The attachment label 50 is attached to the lid 10 while simultaneously covering the gas flow section 20, the first discharge passage 36, and the second discharge passage 38. That is, the first discharge passage 36 and the second discharge passage 38 that are depressed are passages through which gas can flow by the attached label 50.

Next, the operation and effect of the third embodiment of the present invention will be described.

The fermented gas generated from the fermented food in the container 5 is discharged through the through-hole 34.
The fermentation gas 4 can flow the fermentation gas, but the liquid in the container 5 is finely processed so as not to leak, so that the liquid in the container 5 does not leak from the through hole 34 even when the container 5 is inclined.

The fermentation gas that has passed through the through hole 34 is deodorized in the process of passing through the deodorizing bag 44 provided in the rectangular recess 32, and then passes through the first discharge passage 36, and the liquid deodorant 46.
Will go through.

Here, the first discharge passage 36 prevents the liquid drug component in the liquid deodorant 46 from coming into direct contact with the deodorant bag 44 as the activated carbon component.

The liquid deodorant 46 adsorbs and sterilizes external air, and at the same time, prevents external air from flowing into the container 5. Thereby, since the internal pressure of the container 5 is maintained at the atmospheric pressure, fermentation is suppressed, and the inside of the container 5 is filled with carbon dioxide gas or nitrogen gas and packed, whereby the aversive conditions which are the optimum conditions of the fermented food are obtained. Can be maintained. As a result, the freshness of the fermented food can be maintained for a long period of time, and the adverse effects due to alteration of the contents and contact with air can be significantly reduced.

Further, since the deodorizing bag 44 is filled with solid particles of the activated carbon component, it may not be possible to deodorize all of the fermentation gas. It is completely deodorized during the process.

The completely deodorized fermentation gas is gradually discharged through the gas discharge port 75 through the second discharge passage 38.

As described above, according to the present invention, since the fermented food packaging container is made of a light plastic material, the container does not expand due to the pressure of the fermentation gas during distribution. Further, since the container 5 and the lid 10 are sealed without heating, not only the fermentation of the contents can be suppressed, but also the opening of the lid 10 becomes easy. In particular, since the pressure in the container body 5 is always kept constant with respect to the pressure of the fermentation gas generated during the distribution process, safety during distribution can be ensured, and at the same time, the odor generated when the fermentation gas is discharged. Can be exhausted after deodorizing.

The packaging container for fermented foods of the present invention can be applied to packaging of fermented foods such as miso, takuan, natto and the like in addition to the above kimchi.

[0045]

As described above, according to the present invention,
Fermented food packaging containers that are packaged and distributed at kimchi production plants deodorize and continuously discharge fermented gas, so that they do not adversely affect consumers' purchase desires at the time of sale and leave a smell in the sales area There is no such thing. In addition, since safety during distribution can be ensured, it is advantageous for export.

Although the present invention has been described based on specific embodiments, the present invention is not limited to these embodiments.
Obviously, modifications and improvements can be made without departing from the ordinary knowledge of those skilled in the art.
